anyone turbo their FZR?

[match417]

So i'm just playing around online looking for a really small turbo. When I was in Korea, i noticed that about half of the cars on the road said "turbo" on the back, and on the few hoods i looked under, they had a crazy small turbo, something that would probably work great on a bike, but i haven't been able to find any of them online. But what about the "electric turbo's" as they're called on ebay (personally i don't like calling it an electric turbo because it doesn't make a lot of sense calling it that) do they work? It doesn't say much about it or how much psi it puts out.


ebay "electric turbo"

That think looks like it's just a vacuum motor. You're just sucking in air all the time and it doesn't respond to speed change or engine load. I say it's poo.

First, a 12v fan like that would be hard pressed to even bring airbox pressure back to atmospheric at anything over idle.(is that one of yut ughhhhh's other products?)

Second, turbo'd engines aren't just standard engines with a turbo plumbed in. With any kind of appreciable boost, compression needs to be altered(lower) and cam timing has to be optimised for the boost.

This means, below the boost level the engine actually makes LESS power. And carbureting for a turbo is a pretty tricky dealio-most people don't get it right w/o the turbo.

Closed loop fuel injected engines CAN have a small/moderate amount of boost applied without internal modification because the engine management computer is tracking and preventing really bad effects like detonation and is handling the drastic mixture fluctuations that the transistion from n/a to forced induction will cause.

turbo busa producess 499hp...can barely keep the front wheel on the ground.
I only know that someone had on turbo on there fzr1000 drag bike.
there is a picture of it in the "stand out FZRs" thread I posted.
but I guess our weak transmissions cant handle the turbo..it kills second gear...i guess
Iv looking into it before and just gotta a bunch of negative comments from a few members

true, turbo engines aren't regular engines, BUT you can take a regular engine and put a little 6-8 psi turbo on it and pull an extra 100 hp out of it..a car engine of course. The PSI is low enough for the engine to still last if it's done right, it's a great mod for N/A cars like non-turbo 90's celica's, 240sx's, focus's, etc. And if we find a turbo small enough we could definitely put one on the FZR, i would imagine the main jets have to be larger, and maybe the pilot jets, but it would work on low psi without any other mods.

As far as the little ebay electric motor, I really don't think it can push as much air in as the engine sucks in, but best thing it would do would probably be a slightly quicker low end response since more air is there at take off, but at high revs, i doubt it's beneficial at all. I just thought i would ask to see if anyone has found anything yet. It says the motor only draws 3 amps, that's crap man, 3 amps is nothing, give me a vacuum cleaner motor and let me put it in line with the intake.

I would love to get a really small turbo, and probably open up the wastegate a little more so too much air isn't being crammed into the engine. I don't even think you would need a bov at that low PSI. Right now we can run our bikes on pump gas, so that tells me that more air/fuel can be crammed in than what is going in stock. But i'm looking for a tiny turbo for cheap to throw on.

Yamaha couldn't get it sorted out with the seca 650 turbo..hella turbo lag...big piston holes.....lunched valves.....2 year production run...but yeah, maybe you can.


The cars you mention all have FI, and electronic actively controlled ignition and start with a base compression ratio of about 9:1.

Be much better off and much cheaper to go with wet nitrous in my opinion.

not mine...it was on ebay while ago.

Well just to start the project ur going to need a custom header( exhaust manifold) and a metal air box.
Do they make a kit for the YZF? Y not build a 660 with a turbo kit for the YZF? Go big or go home, right?

edit: I don't know what the year changes are on the R6 but what about putting FI from an R6 with the YZF head?

I like cephlopods

Knock those off going around corners.

I'm going to try not to be a downer about the whole thing, but going fuel injected seems mandatory if you're going with a turbo. From some of my conversations with George on the subject of the FZR carbs, I think it's safe to say that adding any pressure to the intake with stock FZR carbs would play hell with them keeping in tune (sorta like some of the problems you hear of with pod air filters). You might be able to modify the YZF carbs to work, but even with a metal airbox, there's still the possibility of blowing out the carb boots. Maybe they're a little more durable than I give them credit for.

But let's just say you decide to buy R6 throttle bodies and a Megasquirt ECU. There's some flywheel modification that has to be done for the Megasquirt crank trigger and alot of wiring. In the end, I would think you'd come out cheaper to buy an entire running R6 motor and turbo it (and you get the added bonus of a beefier transmission).

As for forced induction for really cheap, was browsing the net a month or so back and found some V-Twin guys talking about using the smog pumps off of v8 pickup trucks as cheap superchargers (you know, the air pump in the serpentine belt assembly that pumps air into the exhaust to aerosolize the unburnt fuel as part of the smog system). The only problem with one of those is that you'd have to figure out a way to run a drive belt to it.

Just thought I'd throw all of that out there.

im sure if u know any local wrench heads at your local auto shops talk to them i bet they could come up with somthing .. if they did it in the 80's and 90's on bikes im sure theres a way todo it

[match417]

first off, i don't have FZR carbs anymore..YAY! I have YFZ600 carbs, and it seems like yamaha put a lot of work into the pressure equalization setup on the YZF carbs, the designers probably toyed around with the FZR after it was created just for fun, or if it was their own personal bike, so the pressure equalization system was created...I don't know. Either way, i think the YZF carbs will be able to handle a little boost better than the FZR carbs can. And my first bike was a seca II, nonturbo, it was my learner that i got for free, fixed, learned on, then sold. Anyway, forced induction has come a long was from the mid 90's or whenever it was they produced the seca 650 turbo. And I think the development of the YZF600 carb pressure equalization system might have helped me out on the FZR.

as far as pressure blowing out carb boots, not gonna happen. This is only 1 or 2 psi that i'll be pushing into the bike, probably just 2. I'm not going crazy with it. I've seen silicone couplers blow off of cars pushing 26 lbs of boost, and my old TSi just had stock piping, stock turbo, and an aftermarket BOV with about 17 psi max, no tubing blew out or off. 1 or 2 little psi isn't going to hurt anything. I would like to test it and see if i could make it to 5 psi, but i doubt it would run that great. I would need a lot of different jet sizes though to experiment.

No custom header..each runner has to have the exact same back pressure, or a couple cylinders are going to be able to move more freely than the other ones, creating an imbalance in the engine, resulting in a slight power drop, something around 5% ish depending on the severity of the difference between the cylinders. So if I have my runners bent to where they merge into one for the turbo then either every runner has to be the exact same length with the exact same bends creating the same pressure for each cylinder, or a back pressure test has to be done on each runner and each one has to be adjusted accordingly.. I'm probably going to put the turbo behind the stock collector and try to conceal the long intake pipe as it runs back up to the intake...if i even end up doing any of this, i don't really have time for much of anything these days.

And not forgetting a sufficient oil supply.

I'd love to see you do it. I think it would be quite an adventure AND will show that thte FZR is really the bike of choice for major mods.

OFF-TOPIC WARNING!

Speaking of "mods", when I visit the Gixxer.com forums, usually their "mods" are replacing the stock windscreen for a tinted one or a K&N filter... LAME! They have no idea what a "mod" is.
